You didn't actually ask a question about the fan but I'll guess.
The Sabertooth Z87 includes two small fans to remove the heat, so yes the thermal armor does raise the temp next to the board.
I personally use the Thermal Radar software to STOP the fans unless the temp hits 50degC (hasn't yet) and for 1 minute on shutdown (every time). You don't want the fans on in normal use as they are really annoying (I have the Z77 version but I assume they're the same).

That cooler is fine, however any liquid cooler removes the air flow from near the CPU so the motherboard CPU VRM's can get pretty hot, so I have a bit of problem with that. I also like my CPU fan to flow air across my System RAM but I don't know if that's needed as there's still some air flow via the radiator fans.
The i7-4770K can be slightly overclocked to 4.2GHz without voltage increase (my recommended setting) and use a pretty inexpensive cooler. You'll still want to sort out a fan profile to auto-adjust the speed (Thermal Radar).
Here's a great little CPU cooler:

I like the Asus Maximus Hero VI. It has SupremeFX audio. The Sabertooth does have that 5-year Warranty but otherwise the "armor" is mostly a gimmick though it does protect against clumsy people holding screwdrivers and possibly insane cats.
